Hi coderanch,
im studying struts 1 (the english language too!!

so if i make mistakes, i'm sorry for that), i would like to do an update statement, passing a parameter from a promtbox to mapping action method. May be i could write a form to fill the fields, but seems to be an interesting challenge. In order to do that, i wrote the following code:

-------------------------------------------------------------
//listado.jsp  
         ...
        <script type="text/javascript">
        	function edit_prompt(){
        		var numero = prompt("Nuevo numero:")
        		if(!numero==null || numero!=""){
        			System.out.println("El nuevo numero en la jsp: " + numero);
        			session.setAttribute("numero",numero);
        		}
        	}
        </script>
    </head>
    <body>
      ...
    <logic:iterate id="contacto"
    	        name="contactos"
	        scope="session"
	        type="com.beirut.struts.vo.ContactVO">
		<% 
			Map<String,String> contactMap = new HashMap<String,String>();
			contactMap.put("usuario",contacto.getUsuario());
			contactMap.put("nombres",contacto.getNombres());
			contactMap.put("paterno",contacto.getPaterno());
			contactMap.put("materno",contacto.getMaterno());
			contactMap.put("telephone",contacto.getTelephone());
			pageContext.setAttribute("contactMap",contactMap);
		%>
           ....

<html:link name="contactMap"
	   page="/editaNumeroAction.do"
	   onclick="edit_prompt(); return numero">
	<bean:message key="lilldep.text.edit" bundle="contactResorces"/>					   
                </html:link>
         <logic:iterate/>    
------------------------------------------------------------------------------
//ContactAction.java

public class ContactAction extends MappingDispatchAction{

public ActionForward editaNumeroAction(ActionMapping mapping,
				           ActionForm form,
				           HttpServletRequest request,
	                                                           HttpServletResponse response) throws Exception{
		ContactVO contacto = new ContactVO();
		HttpSession session = request.getSession();
		ContactService cs = new ContactDaoService();
		BeanUtils.copyProperties(contacto, request.getParameterMap());
		System.out.println("request: " + request.getAttribute("onclick"));  // i get a null value
		System.out.println("session: " + session.getAttribute("onclick"));  // i get a null value
		System.out.println("parametro: " + request.getParameter("numero"));  // i get a null value too!!
		//cs.editaTelefono(contacto);
		session.setAttribute("contactos", cs.listaContactos(contacto.getUsuario()));
		return mapping.getInputForward();
	}
------------------------------------------------------------------
//struts_config.xml

i tried too this:
http://stackoverflow.com/questions/739822/problem-with-attribute
but i know now thats incorrect too.

I can populate the prompt box but, i can not pass the value from hyperlink to editaNumeroAction.do.
Is there any way to do that i want (only using struts & Ibatis)?
thanks in advance.
Jonathan.
